I was considering flying out to meet her in DFW but it isn't looking good for that. I will advise her to clear back through security in terminal D and take the tram to the domestic terminal. I am also going to advise her to try to change the last leg only to a later flight. There is another AA flight that departs Dallas 2 hours latter. That would give her 3 hours to debark the 777 clear through customs, recheck her luggage clear security and find the departure gate.
I hope they allow her to make this change.
